PUMP.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed December 16, 1905. Serial No- 292,060.

To all whom it may concern.-

Be it known that I, CARY ALBERT NEY- LAND, a citizen of the UnitedStates, and a resident of Lewiston, in the county of Nez Force and Stateof Idaho, have invented a new and Improved Pump, of which the followingis a full, clear, and exact description.

The purpose of the invention is to provide a construction of pump esecially adapted for irrigating purposes whic will be simple, durable,automatic, and continuous in its action, the pump being particularlydesigned to operate by the current of a body of water, and also to soconstruct the device that two pumps are coupled together to form onecomplete pump, each individual pump having two plungers which operatesimultaneously, but in opposite directions.

The invention consists in the novel con struction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the complete device. Fig. 2 is a sectionalrear elevation of the device, and Fig. 3 is an enlarged verticallongitudinal section through one of the individual pumps.

A represents a float which at its forward portion at opposite sides isprovided with upwardly-extending blocks 10, which blocks have a flatupper surface 10*, as is shown in Fig. 2, and one side is usuallyperpendicular, but the other side is expressly downwardly curved orinclined, as is shown at 11 in said Fig. 2. The said inclined or curvedsurfaces of the blocks are at the same sides thereof or face in the samedirection, as is also shown in Fig. 2.

Two pumps B and B are placed in parallelism, with the float A extendinglongitudinally thereof, as is shown in Fig. 1. Each of the said pumps isin the main of like construction, each pump comprising a suctionpipe 12,which is carried down through a supporting-block 12 on the float andthrough the body of the float, as is shown in Fig. 2, and the saidsuction-pipe at its bottom is provided usually with an attached sleeve18, partially closed at the bottom, and the opening in the bottom ofsaid sleeve is controlled by a valve 14, adapted to open in an upwarddirection. However, it will lce understood that the sleeve 13 may beomitted and the valve 14 be located directly in the bottom of the saidtube. The suction-tube 12 at its upper end is screwed into the bottommember of a crossfitting 15, and at each side of this cross-fitting islocated a tube 16, which is screwed into a side arm or member of thecross-fitting 15, as is best shown in Fig. 3, the said tubes 16 beingopen at their outer ends, and. a plunger in the form of a sleeve 17 ismounted to slide on each tube 16, and each sleeve 17 is closed at itsouter end by a cap 18, screwed thereon or otherwise secured thereto. Atthe inner end of each sleeve 17 a stuffing-box 19 is provided, adaptedto render the action of the sleeves 17 on the tubes 16 air and liquidtight. Each sleeve 17 at its capped end is provided with a guide-rod 20,and these guide-rods 20 have movement in bearings formed in the upperend of standards 21, which standards are secured to the upper face ofthe float A, as is indicated in Figs. 1 and 2.

A collar 22 is connected with each sleeve 17, preferably adjacent to thestuffing-box 19 of the sleeve, and each collar 22 is provided withopposing pins 23. (Best shown in Fig. 1.) Opposing shifting arms 24 arepivoted upon the said pins 23, and the said arms 24 extend outwardbeyond-the guidebars 20 of the sleeves and are connected at their outerends by a cross-bar or cross-head 25. These cross-bars or cross-heads25. have a pivotal connection with straps 26, and,

vertical rocking movement on the said float A in any suitable orapproved manner. These operating-arms C and C extend any desireddistance beyond what may betermed the forward edge of the float A, andeach operating-arm O and O at its projecting rear end is provided with aplate 28, of metalor any suitable material, which extends down ward, soas to enter the water and be operated upon by the action of the current.These operating-arms C and C at that por-' tion which extends over thefloat A are connected with a link 29, the link 29 being pivotallyattached to one arm-the arm 0, for

example-forward of its fulcrum 27 and to the opposing arm C about anequal distance to the rear ofthe fulcrum of said arm, as is illustratedin Fig. 1. In the further construction of each individual pump astandpipe 30 is secured to the upper arm or memer of the cross-fitting15, and this standpipe is usually made in two sections, as isillustrated in Fig. 3, connected by a sleeve 31, forming thereby areceiving-chamber 32 of enlarged diameter, and the lower section of thestand-pipe, which is also a dischargepipe, is provided at its upper endwith a valve 33, which-opens upward in the chamber 32, as is alsoindicated in Fig. 3.

At the upper end of the stand or discharge pipe 30 of the first orforward pump B a sleeve 34 is secured, and a capped extension-pipe 35 issecured to the said sleeve 34, forming an air-chamber 36; but in theconstruction of the individual pump B the parts 30, 34, and 36 areomitted, and in place of the cross-fitting 15 a T-fitting 37 isemployed, connected by a length of pipe 38 with the rear member of thecross-fitting 15 of the forward pump B, as is shown in Fig. 1, and adelivery-pipe 39 is carried from the sleeve 34 below the air-chamber 36to any desired point where the water is to be delivered.

A standard 40 is erected from the edge portion of the float A at or nearits center, and a beam 41, which may be termed a walking-beam, ispivoted to the upper end of the said standard, and the ends of thewalking-beam 41 are connected with the operating-arms C and O to insurecooperation of such parts by attaching rods 41 to said arms and chains41 to the upper ends of the rods, which chains are adjustably connectednear their projecting ends, and these cables are loosely passed througheyes 44, located at the end portions of the walking-beam 41. The cables42 and 43 are carried to an engagement with opposite sides of a drum 45,to which they are attached, the said drum being mounted to turn in thestandard 40. The shaft of the drum is provided with a suitablecrank-handle 46 and a ratchetwheel 47 engaged by a pawl 48, carried bythe sai'd standard, as is shown in Fig. 2, so that t'he saidoperating-arms C and C may be drawn upward, so as to be entirely out ofthe stream when so desired and be held in their upper position. Thecables 42 and 43 should be slack while the arms C C are in motion, so asnot to interfere with the upward and downward stroke of the arms assuspended by the members 41 and 41 The Windlass and cables 42 and 43 areonly used in stopping the power. 'At all other times they hang loose. Across-bar 49 is attached to said standard 40, and links 50 and 50*,together with interposed springs 51 connecting the links 50 and 50*, areattached to the ends of the cross-bar 49 and to the operating-arms C andC, where the cables 42 and 43 are connected with said arms. The springs51 serve to assist the operating-arms C and C in their upward movement.

The normal position of the operating-arms C and C is that shown by fulllines in Fig. 1, wherein their rejecting ends are made to converge and teir inner ends to diverge. In the normal position of the saidoperatingarms 0 and C one arm will be upon the upper resting-surface 10of a block 10, while the other arm will be free from its adjacent block10, and its blade 28 will be in the water to be acted upon by thecurrent, and as the current moves the operating-arm C, for ex ample, indirection of the left-hand side of the device the said arm will ride upupon the left-hand block 10 while the right-hand arm C will be carriedoff from its block, held up by the action of the walking-beam 41, until,when the lefthand arm C shall have been Well seated upon its block 10,the right-hand will be carried outward or in an opposite di- 10o rectionto those of the pump B, and as the arms C and C reverse in action thereverse movement of the plungers of the two individual pumps will takeplace. It will be ob served that by means of the connections 8 whichhave been described the two individual pumps act connectedly as one.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In pumps, a support, operating-arms pivoted uponsaid support, connected for simultaneous convergent movement at one oftheir ends and divergent movement at their opposite ends, two individualpumps coupled to form one complete pump, two plungers for eachindividual pump, operating in opposite directions, and pivotalconnections between the plungers and the said operating-arms.
